On 26 January 1904, Wright was convicted of fraud at the Royal Courts of Justice and given a seven year prison sentence. He committed suicide by swallowing cyanide in a court anteroom immediately afterward.

The inquest also revealed that he had been carrying a revolver in his pocket, presumably as a backup: he was never searched as the security was weaker at the Royal Courts, which were of course Civil Courts, the trial being held there as it was deemed likelier that the special jury required would be less prejudiced against the accused than a normal jury at the Old Bailey criminal court, which was in the City.

In spite of his financial errors, there was a great outburst of grief at his funeral at Witley where he is buried.
